I purchased the Canadian mats in April and they are the new style as well. Just tested the rivets and bar with a magnet and it doesn't stick so it's safe to assume the fasteners are all aluminum. Although they won't corrode as fast as steel rivets, the salt will eventually attack the aluminum so the suggestion to apply some silicone still stands.I have also contacted the manufacturer to find out what kind of material is used in the pins going through the mat and if I need to do anything to prevent future corrosion, such as put silicone on the pins. I'll report back later on what they tell me. I assume that the BD Maxpider's will have the same upgrade in how the badges are attached.
